Shrink sleeves offer a lot of benefits to brand owners such as label landscape for product promotion, placement of information and scope for creation of decorative packaging. The shortcoming for shrink sleeve labels is, however, recycling. The issue of sustainability and recycling that still continues to muddle the label and packaging industry. This kind of label mandates removal before recycling the pet bottles.
Findings on Sleeve Label Material
Recyclers, nonetheless, have witnessed progress on shrink sleeves. They are working hard to find feasible solutions to difficulties encountered in recycling containers that use shrink sleeve labels. Things are getting much better for the future recyclability of shrink labels. According to the Association of Postconsumer Plastic Recyclers (APR), a trade group, new label technologies are commercially available from many suppliers.
The challenge that exists now is to drive these technologies into actual commercial use. APR is hopeful about the future of shrink sleeves’ recycling. More and more companies today are creating sleeve label film that is easily separable from the PET bottle at the time of recycling. Historically, sleeve label material has been made from glycol-modified PET or PVC. Both PET and PVC plastics sink in water and mix with PET flake. The development of new polyolefin label by a few of the label manufacturers, however, offers an option for label pieces to float in a separation tank.
Recommendations of the APR
Companies using shrink labels need to follow the recommendations put forth by the APR. It recommends companies to use sleeve labels that remain afloat in water and isolate them from PET flakes in a sink or float material separation step. They also recommend using printed label inks that do not stain PET flakes while washing or rinsing during the recycling process. It is necessary for companies to use an APR guidance document to examine the effect of a label on PET bottle recycling. Moreover, they need to utilize shrink sleeves labels that leave minimum 20 percent of PET bottle surface area open.
Research of the APR in 2013 showed recyclers spending about two to four cents per pound of reprocessed plastic to remove shrink sleeves. The use of these labels registered seven to nine times growth from 2007 to 2013.
The Road Ahead
Brand owners of consumer goods are mindful of sustainability and recycling issues when it comes to shrink labels. They are all set to adopt easily recyclable shrink-sleeve label film. Renowned companies such as Coca Cola shifted to recyclable shrink sleeve material for its holiday orb bottle. The big challenge, however, is the pace at which the companies can push the use of recyclable shrink sleeves label.
